I had a lot of fun in reading Sherlock Holmes and the Count Dracula and had a lot of fun in read this follow up which features a lot characters from the previous books.
It's a good mix of horror, historical mystery with a pinch of humour and a Holmes nearly canonical.
It's gripping, fast paced and highly entertaining.
It can be read as a stand alone but it will be more enjoyable if you read the books in order.
Highly recommended.
Many thanks to the publisher for this arc, all opinions are mine
